Title: Manufacture of artificial lawn
Inventor: UEMATSU TOMOKO
IPC: E01C13/08
Filed: 1994-10-07
Abstract: PURPOSE: To increase anti-restoring property, form the shape into similar appearance to natural lawn, and secure heat resistance by controlling the temperature distribution of synthetic resin-made sheet parts and, after heating and pressurizing, cooling the sheet parts for freezing strain. CONSTITUTION: A thermoplastic resin is fed from the nozzle of an extruded head 12 on the outer peripheral surface of a forming drum 11, and a sheet part formed integrally with a base part is formed continuously sequentially in the direction of rotation of the forming drum 11. In this case, a lawn body formed by a long artificial lawn forming device 10 is fed to a texture treatment device 20 through a dancer roll 23. Also an infrared radiator is arranged in a heating zone 21 at upper and lower surfaces of the lawn body, and multiple long base parts are arranged at a specified interval. Next an artificial lawn 1a with a construction in which sheet parts are arranged between the base parts longitudinally at a specified pitch is obtained, and post-processed by a texture treatment device 20. Thus the artificial lawn 1b obtained by processing the sheet parts in the form of artificial lawn is provided so as to relieve the directional property and residual strain in forming. Thus poor corrugation, etc., can be prevented from occurring.

Title: Developing device
Inventor: ONO TAIZO
IPC: G03G15/08
Filed: 1985-10-31
Abstract: PURPOSE:To detect whether a developer exists on a rotating body or not, and to detect the remaining quantity of the developer with the high reliability, without requiring a new element, by providing a detecting means for detecting a current value, on a voltage applying means placed between a moving body and the rotating body. CONSTITUTION:When a developing roller 22 rotates, and an electrified toner 19 on the surface passes through a blade 28, it is scraped down partially and controlled to a prescribed toner layer thickness. Subsequently, when a minus-electrified latent image on a photosensitive drum 13 is opposed to a plus-electrified toner 19 on the surface of the developing roller 22, it flies and a development is executed. In this state, the toner 19 of a proper quantity exists in the fur 25 of a fur brush 23, and since the contact resistance between the fur brush 23 and the developing roller 22 is high, the current value of a detecting means 27 is small. Next, when the development process is repeated and the toner 19 in a hopper 20 and the toner 19 in the fur of the fur brush 23 are used up, the contact resistance of the fur brush and the developing roller 22 becomes low, therefore, the current value of the detecting means 27 becomes large. In this way, the remaining quantity of the toner 19 in the hopper 20 can be detected.

IPC: H04L69/40
Filed: 1991-09-25
Abstract: PURPOSE:To loop back an incoming signal onto an outgoing signal without a delay by allowing a relay station to use a number of a master station as a relay number of its own station in a number calculated based on a relay number of a host station in response to its state. CONSTITUTION:When a frame synchronizing circuit 25 of a relay station Rm cannot detect a frame synchronization pattern, the relay station Rm discriminates it to be in a frame asynchronous state and outputs a frame pulse in itself through self-running oscillation and informs the asynchronization state to a loopback control circuit 24. The circuit 24 sets a loopback circuit 13 to loop back an incoming signal to an outgoing signal and informs the loopback state to a relay number arithmetic operation circuit 26. The circuit 26 sets a relay number as a relay number '0' of the master station and outputs the result and the output is multiplexed with a frame synchronization pattern (101) by a multiplexer circuit 11 and the result is sent to a subordinate station Rm+1, the received relay number is set to '0', and the circuit 26 of the subordinate station Rm+1 outputs '1' as it relay number, then a fixed delay of (n-1)t to the incoming signal.

Abstract: PURPOSE:To reduce the distortion in an output data signal by providing a 1st level difference having a correlation and a 2nd level difference without correlation and outputting an interpolation video data to vary the output data smoothly at the intermediate level difference. CONSTITUTION:A gradient of a part (d) is changed into a gradient (g) in a range Y to interpolate the parts (d,f) linearly. That is, a value (A+B)+f(A-B) being an arithmetic output of input data A and a delayed data B is outputted from a 2nd adder 45, and halved by a divider 46 to form an output signal C. That is, C={(A+B)+f(A-B)}/2. In interpolating the gradient (g) in the range Y linearly, since step difference is eliminated, the signal distortion is improved.

IPC: B66B5/02
Filed: 1988-09-29
Abstract: PURPOSE:To permit an elevator to be suspended even by one operator positively with ease by sounding a buzzer for warning intermittently as a cage comes close to a specified position for suspension, and thereby constituting the intermittent interval of sounding to be made shorter gradually. CONSTITUTION:When a cage is suspended because commercial power has stopped and so on, an operator in an elevator machine room turns a power supply switch SW on, manually actuates the brake lever of a braking mechanism thereafter so as to gradually release the lock of the rotating shaft of a sheave so that the cage gradually comes close to a specified position for suspension. A floor position judging section 3 compares the detected signal from a pulse counter 2 with the floor position data signal from a floor position data section 4 so that the present position of the cage is judged from time to time. And as the cage gradually comes close to a specified position, the pulse interval produced by a buzzer control section 7 is designed to be made shorter depending on the distance between the present position of the cage and the specified position.

Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce number of operation switches and to improve the operability by interlocking opening/closing of an upper cover with on/off control of a power supply. SOLUTION: A hinge turning angle sensor 127 senses a turning angle of a hinge and a CPU 121 controls a power supply to be supplied to a camera main body and a monitor 122 when the sensor 127 detects it that the open angle is 45 degrees or over.

Through the constitution above, number of operation switches for on/off control of the power supply is reduced and the steps of operation procedure are decreased to improve the operability.  Moreover, useless power consumption by the user that leaves the power supply unswitched is avoided and the camera with low power consumption is realized.
